The Tokina 18mm T1.5 Cinema Vista Prime Lens with a PL mount and with focus scales marked in feet provides an image circle that more than covers full-frame sensors and is designed to provide sharp images even when recording images at 8K resolution. This is an 18mm focal length lens, and it shares the same form factor, lens gear position, focus rotation, and front barrel diameter as the other Tokina Cinema Vista prime lenses. This makes on-set lens changes a fast and efficient operation. It features a maximum T stop of 1.5, useful when shooting in low-light situations or when you want to capture that exceedingly shallow depth-of-field look.
